为制定中国老年前期男性红细胞压积参考值的统一标准提供科学依据，收集了中国各地用温氏法测定的健康老年前期红细胞压积参考值，并对其与地理因素的关系进行了研究，发现海拔高度是影响老年前期男性红细胞压积参考值最主要的因素，随着海拔高度的逐渐增加，老年前期男性红细胞压积参考值也在逐渐的增大，相关性很显著，用逐步回归分析的方法推导出了一个回归方程．如果知道了中国某地的地理因素，就可以用回归方程估算这个地区的老年前期男性红细胞压积参考值，依据老年前期男性红细胞压积参考值与地理因素的依赖关系把中国分为青藏区、西南区、西北区、东南区、华北区、东北区等六个区．
To provide a scientific basis for the development of a unified standard for reference value of pre-senile men’s hematocrit in China, and to collect the reference value of pre-senile hematocrit as determined by the Wen’s method in various parts of China, and to study the relationship with the geographical factors Altitude is the most important factor affecting the pre-senile male hematocrit reference value. With the gradual increase of altitude, the pre-senile male hematocrit reference value is also gradually increased, the correlation is significant, with stepwise regression analysis The method deduces a regression equation. If you know the geographical factors of a place in China, you can use the regression equation to estimate the pre-senile men’s hematocrit reference value in this area, according to the pre-senile male hematocrit reference and geographical factors dependent on China is divided into Qinghai- Southwest, Northwest, Southeast, North China, Northeast and other six districts.
